Wireless Relay Energy Management for Home Appliances
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for energy conservation in home appliances are ineffective as they lack real-time monitoring and control, leading to increased energy consumption and carbon emissions, as users are unaware of their energy usage until receiving utility bills.
Innovation Solution
A wireless control system that monitors energy consumption across various appliances and initiates an energy conservation mode when usage exceeds a predetermined threshold, reducing energy consumption by adjusting operational parameters without cutting off the energy supply, using a relay device with RF transceivers and a processor to send control commands to appliances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If passive energy conservation methods (turning off lights, adjusting AC temperature) are used, then energy consumption is reduced, but user convenience and awareness of energy usage are deteriorated
Solution Approach 1:
The system implements real-time feedback by monitoring energy consumption of appliances and notifying users when thresholds are exceeded. The relay device receives consumption data from the energy monitoring period, compares it with thresholds, and sends notifications to user devices, enabling users to make informed decisions about their energy usage patterns.
Solution Approach 2:
The relay device acts as an intermediary between the energy monitoring system and user devices. It receives energy consumption data, processes it by comparing with thresholds, and communicates with user devices to provide information about energy usage, thereby bridging the gap between passive consumption and active user awareness.
2Loss of energy
If energy conservation mode is activated to reduce energy consumption, then energy efficiency is improved, but appliance operational capability may be deteriorated
Solution Approach 1:
The system dynamically adjusts energy conservation measures based on real-time consumption data and user responses. When energy consumption exceeds the second threshold, the system enters energy conservation mode and sends control commands to appliances to adjust their operation, but allows users to override these commands if needed, making the system adaptable to user needs while promoting energy efficiency.
Solution Approach 2:
The system changes operational parameters of appliances during energy conservation mode. The relay device sends control commands to adjust appliance parameters (such as power levels, operational intensity) to reduce energy consumption while maintaining basic functionality, rather than completely shutting down appliances.
3Productivity
If real-time energy monitoring and control is implemented, then energy conservation effectiveness is improved, but system complexity is deteriorated
Solution Approach 1:
The relay device performs multiple functions: it acts as a communication relay between wireless networks and appliances, monitors energy consumption data, compares consumption with thresholds, sends notifications to users, and transmits control commands to appliances. This multi-functionality reduces the need for separate dedicated devices for each function, thereby managing system complexity while achieving effective energy conservation.

AI summary
A method of managing energy consumption which is applied to a wireless control system is provided, wherein the wireless control system includes a plurality of appliances and a relay device. The method includes the steps below: first, obtain an amount of energy consumption from a start time point to a predetermined time point in an energy monitoring period; next, compare the amount of energy consumption with a second threshold during the energy monitoring period, which is lower than a first threshold; finally, if the amount of energy consumption exceeds the second threshold, determine whether to start an energy conservation mode; if the energy conservation mode starts, the relay device sends an energy conservation command to at least one of the appliances to control said appliance to consume less energy. Whereby, in the energy conservation mode, the energy consumed by the appliances would be reduced without stopping the energy supply.
